Sort by

Looking for high‑quality Honda CB400F parts? Whether you ride a 1975, 1976, or 1977 CB400F, this collection has everything you need to restore, maintain, or customize one of Honda’s most charismatic vintage motorcycles.

The Honda CB400 Four is a true gem of the 1970s. Produced from 1975 to 1977, this four‑cylinder, four‑stroke classic was designed in the spirit of Honda’s larger Four models but scaled down for agility, style, and everyday usability. Its sweeping chrome four‑into‑one exhaust system, culminating in a distinctive megaphone silencer and polished collector box, became an iconic design feature admired by riders and collectors.

Under the engine cover sits a 398cc SOHC inline‑four with dual carburetors and a responsive powerband that made the CB400F feel lively and refined for its class. Its balance of smooth multi‑cylinder performance and lightweight handling gave it a cult following that continues today among vintage Honda enthusiasts, restorers, and custom builders.
